Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977912, here are decompositions:

31 + 977881 = 977912
109 + 977803 = 977912
151 + 977761 = 977912
193 + 977719 = 977912
241 + 977671 = 977912
283 + 977629 = 977912
373 + 977539 = 977912
499 + 977413 = 977912

Showing the first eight; more decompositions exist.
